@ Gopal & Aashish,
Don't live in the world of assumptions....
Why to gift mother and why not to gift father?
or why to gift sister and why not gift brother?
or why to gift your neighbour and why not to gift your own uncle?
and the list will go on...............
Better get a full stop on your question of threats.
Make a Note: A self acquired property why any means on whomsoever name has sole and whole right of himself/herself who owns the property by name.
There is No question of threat from any body and from anywhere to acquire it legally without his/her consent.
Now come to your question whether not to gift father as it will come under inheritable property.
Answer: An inheritance claim comes when the successor of the previous one dies and left for the subsequent successor that is his son.
So,if you will gift him it will neither come under inheritable property becauze it has not come from the inheritance as you are not the Baap of your Baap.Think over it...!!!
The property which you will gift him will come under self accquired proeprty once his will flourish as the sole owner of such property.
Now why to gift mother and not father?
Answer: Read HSA 1956
My opinion is same as above paras.
The women till she is alive no one can claim her property and neither it comes under inheritable property.
It's her children & husband will get the share after her death.
Therefore,to whom ever you will gift a property that property legally belongs to him/her. There is no question of threat from any body if he/she writes a will for such acquired property before his/her death.
